With the development of the times, the new generation of young consumers have higher and higher requirements for the appearance and design of cars, but the problem of driving safety can not be ignored. It can be said that "good-looking leather bags and excellent safety quality" are more in line with current cars. The trend of the market.
Take the popular dongfeng T5 EVO, the pioneer of the fashion brand SUV that just went on the market as an example. Once the model was released, it was called "the second most beautiful SUV" by netizens because of its superb looks. The pre-sale order exceeded 28,587 units.
In order to verify the strength of the new car, on March 28, the China Automotive Technology and Research Center will announce the results of the vehicle dismantling test of the Dongfeng joyear T5 EVO model in Tianjin, and pass eleven rigorous tests to comprehensively test the safety and quality of the model.
■The first dismantling of the whole network, quality test "6+1"
As we all know, the car body is assembled from several parts, and the robustness of the vehicle largely depends on the impact resistance of these key components.
In the production and manufacture of automobiles, the material selection and shape design of key components are particularly critical to improve vehicle safety.
In this test, engineers will disassemble the three key parts of the Dongfeng joyear T5 EVO's anti-collision beam, car body and B-pillar.
Using ultra-high-strength impact tests to simulate the extreme capabilities of these key components during vehicle accidents.
Different from the conventional vehicle crash test, the vehicle dismantling test can make these key components face the challenge directly and show the passive safety performance of the vehicle more intuitively.
At the same time, the China Automobile Center will conduct six quality tests on Dongfeng joyear T5 EVO based on the Chinese automobile market and road conditions.
Many consumers are concerned about the equivalent 100,000-kilometer durability test, vehicle VOC test, and comfort test. The six tests will further evaluate the quality of vehicle models and provide theoretical and data references for consumers to purchase cars.
■The Mount Tai is topped, and the container weighs heavily on the body-in-white
When it comes to passive safety systems for vehicles, we usually think of common components such as seat belts, airbags, and collapse energy-absorbing structures of vehicles, while the white body of a vehicle is often overlooked by us.
The white body can not only affect the posture and appearance design of the vehicle, it is more like the human skeleton, which plays a key support and protection role.
When the vehicle rolls or rolls over, the white body will provide the last safety barrier for the people inside the vehicle.
In this heavy pressure test, the test personnel will use the container to vertically press down the body in white of the Dongfeng joyear T5 EVO.
Through the accumulation of the number of containers, the maximum downforce that the body can withstand is tested, and the compression capacity of the vehicle body frame is demonstrated with more intuitive data.
■Facing the challenge, heavy machinery rolled the anti-collision beam
In daily life, it is relatively rare for vehicles to roll over or crush as a whole, but accidents of rear-end collisions of vehicles do occur from time to time. In the event of an accident, the force generated by the collision will be transmitted to the body frame through the bumper and the anti-collision lower cross member.
It can be seen that the anti-collision beam plays a very important role in the protection of vehicle rear-end accidents.
But because the anti-collision beam is hidden behind the bumper, this makes it impossible for ordinary consumers to conduct direct and effective comparison and testing.
In this rolling test, the tester will put the anti-collision beam of Dongfeng joyear T5 EVO on top of the dummy. The comparison between the rolling of various heavy construction machinery and the state of the dummy under the beam is intuitive for consumers. Shows the material strength of the anti-collision beam of this model.
■Break the limit, fire the door steel beams with live ammunition
In addition to front-end rear-end collisions, vehicles also have a high probability of being impacted from the side.
At this time, the door anti-collision beam will play an important role in protection, but unlike the front anti-collision beam, the narrower depth layout and crumple space place higher requirements on the material and structural design of the door anti-collision beam.
In this test, the testers will use different firearms to shoot live ammunition on the door anti-collision beam of the Dongfeng joyear T5 EVO in a professional shooting range.
With the help of a high-speed slow-motion machine, we will see the wonderful moment when the bullet hits the door anti-collision beam. This test not only has great visual impact, but also allows us to have a deeper experience of the strength of the vehicle door anti-collision beam.
■ Extreme bumps, galloping through the speed bump
If the strength of key components is "collision-induced", then the increase in body rigidity not only provides protection for our driving safety, but also improves the driving control and riding comfort of the vehicle.
Not only that, a vehicle with good rigidity will have a stronger integrity and reduce the possibility of abnormal noise or even deformation of the body during long-term use.
The testers will drive the Dongfeng joyear T5 EVO at different speeds to test the body rigidity and chassis vibration performance of the vehicle through deceleration.
We judge the bumps of the vehicle by observing the changes in the amount of water in the champagne tower in front of the vehicle.
